Answer:
225 flies
Explanation:
Let gene for body colour : A
Let gene for eye type : B
Parent 1 : normal body and normal eyes = AABB
Parent 2: ebony body and eyeless = aabb
F1 : AABB X aabb = AaBb ( all have normal body and normal eye )
F1 progeny is self crossed given that the two genes are on different chromosomes which means they show independent assortment:
AaBb X AaBb =
A_B_ = normal body, normal eyes = 9
aaB_ = ebony body, normal eyes = 3
A_bb = normal body, eyeless = 3
aabb = ebony body, eyeless = 1
Hence the ratio is 9 : 3 : 3 : 1
Out of the 400 flies:
(9/16) * 400 = 225 flies have normal body colour and normal eyes
Answer:
The vagus nerve has two bunches of sensory nerve cell bodies, and it connects the brain stem to the body. It allows the brain to monitor and receive information about several of the body’s different functions.
Explanation:
The vagus nerve is the longest and most complex of the 12 pairs of cranial nerves that emanate from the brain. It transmits information to or from the surface of the brain to tissues and organs elsewhere in the body.
There are multiple nervous system functions provided by the vagus nerve and its related parts. The vagus nerve functions contribute to the autonomic nervous system, which consists of the parasympathetic and sympathetic parts
The vagus nerve has a number of different functions. The four key functions of the vagus nerve are:
-Sensory: From the throat, heart, lungs, and abdomen.
-Special sensory: Provides taste sensation behind the tongue.
-Motor: Provides movement functions for the muscles in the neck responsible for swallowing and speech.
-Parasympathetic: Responsible for the digestive tract, respiration, and heart rate functioning.
